Answer to Question #279230 in General Chemistry for Emre

Question

When 1 mole of this fluorocarbon compound was completely combusted in a bomb

calorimeter, it liberates 3870 kJ of heat which causes the temperature to increase from

25 °C to 26.5 °C. Compute the heat capacity of the bomb calorimeter?

Answer 1

q_cal = C_cal (T2-T1)

q_cal = -q_rxn

C_cal = -q_rxn / (T2-T1) = -(-3870 kJ) / (26.5 - 25) = 2580 kJ/⁰C
